Abstract: An endoluminal catheterization device for providing protection against distal embolization of atherosclerotic debris and thrombi emboli resulting from an endoluminal catheterization procedure. The device is adapted to the new TAVI/PAVI methods to prevent the severe risk of brain embolization and stroke. The embolization protection device may also be an integral part of any other intra-luminal treatment or diagnostic device that may induce embolization, such as a balloon, stent, TAVI or atherectomy.

Abstract: A device and method for balloon and stent angioplasty for treating atherosclerosis with a distal embolization protection component. The device includes an endoluminal dilatation balloon formed on a shaft having at least one lumen, a flexible filter mounted on the shaft, distal to the balloon and a filter deployment memory ring circling the proximal opening of the flexible filter for the purpose of controlling deployment and collapsing of the filter. When the endoluminal dilatation balloon is inflated for the purpose of dilating plaque that is blocking a blood vessel, the flexible filter deployed prior to balloon inflation, traps atherosclerotic debris and thrombi emboli that are released from the plaque, thus allowing blood flow to continue without interference during the angioplasty procedure. At the end of the procedure the flexible filter, containing the debris, is pulled and collapsed into a small profile and is pulled out of the artery as an integrated unit with the balloon.
